Dangerous ladders, particularly those at roof level, are a tragedy waiting to happen. The answer is to develop a practical action plan in accordance with the hierarchy of controls, budget for it and implement it. A great starting point and one prescribed in the OHS Act is a height safety risk assessment of your workplace.
Thoroughly inspect the access equipment to AS and consult with the people using the equipment. Your liability will be reduced and, more importantly still, you will be responsible for a safer workplace. Back to Blog Ladders, steps and stairs. What to use and when Ladders are pretty straightforward, right? Related Articles News. National fall prevention specialists. Maximum angle with a horizontal line: 45 degrees.
Minimum effective tread depth: mm 11 in. Minimum effective width of stair: mm 2 ft. Stair landings: not less than mm 2 ft.
Guard railings should be constructed of structural steel shapes or pipe. Any pipe railing should be seal welded to prevent internal corrosion. Landings If a stair has a vertical rise of 6 m. A single-tier stair rail is used to maintain balance while going up or down stairs, and should be installed on the enclosed side of stairs.
A two-tier rail, used to maintain balance and prevent falls from stairs, should be installed on all open sides of stairs. Stairs with three or more steps should be equipped with stair rails.
Stairs wider than mm 88 inches should be equipped with a single-tier stair rail in the center. Stair rails should be highly visible, often of a different color from the stairs themselves. Toeboards are required if a person could slip under a railing. Stair Treads Each tread should be painted to make its leading edge visually distinctive from the color of the rest of the tread or the walking surfaces to which it is connected.
Ladders Ladders are typically used in the following applications: Access to elevated tanks, towers and overhead traveling cranes; Secondary access and escape; Maintenance access to platforms or other access which are used infrequently or where stairways are impractical. Dimensions The design and installation of fixed ladders should consider the following guidelines all measurements are approximate, and will vary according to local standards and regulations : Ladders should be vertical whenever possible.
Fixed ladders should be straight throughout their length. Ladders should be oriented so that a person faces the structure or vessel while climbing.
Side access ladders are preferred to the front access style for the reasons referred to above.

The minimum clear length of rungs or cleats should be 0. Rungs and side rails should be free of splinters, sharp edges, burrs or projections which may be a hazard. Side rails which might be used as a climbing aid should be of such cross sections as to afford adequate gripping surface without sharp edges, splinters, or burrs.
The perpendicular distance on the climbing side of the ladder from the centerline of the rungs to the nearest permanent fixed object should be 1 meter or more. The perpendicular distance on the back side of the ladder from the centerline of the rungs to the nearest permanent fixed object should be mm or more, except when unavoidable obstructions are encountered.
The step across distance from the nearest edge of the ladder to the nearest edge of equipment or structure should not be more than 0. Ladder rungs should be equally spaced throughout, including the first rung below the landing. Ladder extensions should extend at least 3 meters above parapets and landings.
Rung spacing should be around 0. A barrier should be placed on the back side of ladders that could be inadvertently climbed on the wrong side.
Ladder rungs should be made of steel, protected from corrosion, and made of non-slip materials. Maximum heights of unbroken ladders should be 30 ft. Where vertical ladder heights exceed mm 30 ft. There should be a rest platform every 10 meters. Stairs Illustrations. Popular Comparisons.
